Question

Which condition must hold for two events to be exhaustive?

पर्याय

• \(A \cup B = S\)

• \(A \cap B = S\)

• \(A \cap B = \varnothing\)

• \(A \cup B = \varnothing\)

Answer 1

Exhaustive events together cover the whole sample space. Their union therefore contains every element of \(S\).
